Haynes and Chiltons "shop manuals" are little better than a generic guide since they try to cover too many model years and models in one thin manual. I wouldn't waste my $$$ on either of them. They barely cover the basics and then aren't usually specific on anything. Much of their stuff says things like "should look like this"... not what it actually looks like for your specific model year.
The only comprehensive manual that thoroughly covers your exact model year is the Mopar Factory Service Manual. These are what the Jeep dealership mechanics use and they are absolutely thorough and complete for every conceivable job. You can usually find used FSMs (sometimes new too) on eBay. Caution, some of the cheap FSMs are actually nothing more than a DVD that you have to look at on your computer... not too handy for the garage. Get a printed FSM for your specific model year and life will be good.
